Application iiledMarch 7, 1893. Serial No. 464,975. (No model.)

To a/ZZ whom it may concern/.-

Be it known that LJOHN HILL WHITING, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements inV Tumbling-Barrels, ofwhich the following is a specification, reference being had therein tothe accompanying drawings. v

The invention consists in the peculiar construction of a tumblingbarrel, particularly designed for cleaning car wheel castings, andfurther in the construction of the tumbling barrel whereby the wheels orother articles to be cleaned may be held in a fixed position therein,and separated so as to allow the moving pieces to thoroughly clean thesides of the castings, or in other words to so secure the Wheels orother castings in the tumbling barrel as to cause them to formpartitions, providing the tumbling barrel with a number of separatecompartments.

The invention further consists in the peculiar construction of thetumbling barrel in sections whereby it may be made up in differentlengths, or it may be easily repairedV in part as it wears out.

The invention further consists in the peculiar construction, arrangementand combination of the various parts, all as more fully hereinafterdescribed.

In the drawings, Figure l is a side elevation of my improved tumblingbarrel, showing the two parts separated, and the car wheels in position.Fig. 2 is a central cross section through the barrel, the two partsbeing locked together ready for the operation. Fig. 3 is a longitudinalsection on line :c in

Fig. 2.

My tumbling barrel consists of two heads A and B, to which are secured,centrally, in any desired manner, shafts A and B', which form journalsfor the tumbling barrel, being provided with suitable driving mechanism,such as shown at the left hand of Fig. 1. To these heads are secured twosemi-cylindrical halves O O of a barrel, of any desired construction.One of these halves is detachably secured to the heads, but both may be,and I have shown both detachable in the drawings. They are provided alsowith means for securing them together when the barrel is to be rotated.`They are also provided with interior grooves a, and anges b. The groovesa are of a proper shape to receive the flanges c of the car wheels, andthe anges or ribs b are of 'a width greater than the face yof the treadof the wheel, so that when a number of wheels are placed into a tumblingbarrel, and the ,two halves are clamped together about them, the iiangesof the wheel entering the grooves will hold the wheels apart and clampthem tightly in position, so that the material which is placed betweenwill thoroughly cleanse both sides of each wheel by tumbling against thesame in the usual manner.

In manufacturing my tumbling barrel I preferably make each half incorresponding sections D, each section being provided with a centralapertured lug or rib E, through which the tie bolts F pass. The endsections G are provided with an overhanging ange H adapted to be boltedto a corresponding flange I on the heads. At the edges of each half Ipreferably provide every other section D with an apertured lug or rib J,while the alternate sections are provided with the laterally extendingflanges K, through which the clamping bolts Lk pass for clamping the twohalves together, tiel-ods M passing through the sleeves .I and over theflanges K, as plainly shown in Figs. 1 and 2, firmly tying together allthe sections of each half. This enables me to make up a tumbling barrelof any desired length, that is, I can arrange one for one wheel, twowheels, or nine more or less. The interiors of the heads are preferablyprovided with wear plates O.

The parts being thus constructed their operation is as follows: One halfof the'tnmbling barrel is usually left permanently connected with theheads', as shown in Fig. l. The wheels are then rolled up an inclinedway and into that half with their flanges engaging in the grooves auntil the tumbling barrel is lled, as shown in Fig. l. The scrapmaterial is then filled in between the wheel, the upper half is loweredand the two halves secured together by means of the clamping bolts L.

What I claim as my invention is- 1. In a longitudinally divisibletumbling barrel, the combination with the barrel having closed sides ofmeans for clamping the parts IOO together, and continuous ribs andgrooves for holding the articles to be cleaned in fixed position within,substantially as described.

2. In a tumbling barrel, the combination of two imperforated halves,means for clamping the halves together, and separated continuousbearings in each half, of a shape corresponding to the periphery of acar Wheel, substantially as described.

8. In atumbling barrel, the combination of the heads, of twosemi-cylindrical imperforated halves, consisting of segmental circularsections clamped together and secured to the heads, substantially asdescribed.

4. The combination of two heads, of shafts centrally secured to saidheads and means for imparting motion thereto, and two semicylindricalimperforated halves composed of segmental circular sections, clampedtogether and secured to heads and means for securing the two facestogether, substantially as described.

5. In a tumbling barrel, the combination of the heads, the twosemi-cylindrical halves, detachably secured together and to the heads,each half composed of a series of segmental circular sections havingcomplementary grooves and flanges a and b, substantially as described.

6. In a tumbling barrel, the combination of the heads, of thesemicylindrical halves composed of sections D having the centrallyapertured ribs E, the tie bolts F passing through said ribs 4andclamping the sections together, the marginal apertured ribs .I andflanges K on the alternate sections and the tie bolts M passing throughthe ribs and over the flanges and the clamping bolts L, substantially asdescribed.

In testimony whereof I afiix my signature in presence of witnesses.
